REXA XPAC Series 3 Electraulic™ Actuators for Precision Control in Demanding Environments

The REXA XPAC Series 3 is a high-performance actuator system designed for critical control applications in the most challenging industrial environments. Utilizing REXA’s proprietary Electraulic™ technology, the XPAC Series 3 combines the precision of electric control with the power and reliability of hydraulics, delivering unmatched positioning accuracy, responsiveness, and long-term durability.

What is Electraulic™ Technology?

Electraulic™ actuation is REXA’s patented approach that merges electric motor control with a closed-loop hydraulic system. Unlike traditional hydraulic systems, Electraulic™ actuators are self-contained, sealed, and require no routine fluid maintenance, making them ideal for remote or hard-to-access installations. The system’s motor and pump module precisely regulates oil flow and pressure to drive a double-acting cylinder, ensuring smooth, accurate movement with minimal energy consumption.

XPAC Series 3 Configurations
